JB/T 3592.1-1999 This standard is a revision of JB 3057-82 "Basic parameters of automatic cold heading machine for steel balls". This standard specifies the basic parameters of automatic cold heading machine for steel balls. This standard is applicable to automatic cold heading machine for steel balls for cold heading of steel ball blanks. The ultimate tensile strength of the workpiece material is equal to 750MPa. In order to expand the processing range of the machine, the machine can also be used for hot heading of steel balls. This standard was first issued in April 1982.
